Within the nucleus of an atom you’ll find protons and neutrons, particles that control the properties of any given element. Where the nucleus emits radiation, we find radioactive materials. These materials can be used in lots of ways, including power generation, medical treatments, archaeology, and detecting other molecules.
One scientist in this zone makes computer models to test new nuclear reactor designs, another studies subatomic particle collisions at the Large Hadron Collider, and another examines the tiniest particles in the universe with the biggest science experiment in the world. Another scientist makes people radioactive, but in a good way, not a “Hulk Smash” kind of way!
